        P761 (Pressure gauge with inline type diaphragm seal) P762 (Pressure gauge with extension type diaphragm seal) P763 (Pressure gauge with pad type diaphragm seal)

        Service intended

        Pressure gauge with diaphragm seal are suitable for the situation where the process medium would corrode the instrument connection and pressure sensing element. Furthermore, this type of gauge is suitable for corrosive, highly viscous, crystallising or hot pressure media. Additionally, it is recommended to be used where the process medium might freeze or solidify the instrument connection and pressure sending element due to the ambient or process temperature change and where the process medium requires the flusing from the system to prevent any contamination.

        Design Internal diaphragm
        Accuracy Refer to gauge model
        Suitable pressure range (MPa, kPa, bar) -0.1 ~ 0 to -0.1 ~ 2.5 MPa
        0 ~ 0.1 to 0 ~ 35 MPa
        Filling liquid Silicone oil
        Working temperature Temperature rating of the diaphragm seals depends on the fill fluid, the diaphragm material and the lower housing material. Standard fill fluids are available for temperature range -20 ~ 200 ?C
        Diaphragm material Diaphragms are available in many corrosion resistant materials. Compatibility of selected material and process fluid is the responsibility of user
        Temperature effect Accuracy at temperature above and below the reference temperature (20 ?C) will be effected by approximately
        ±0.5 % per 10 ?C of full scale
